SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 596,611, datedJanuaryd, 1898.

Application filed March 1 8, 1 89 '7- To aZZ whom it may concern: I

Be it'known that I, STEPHEN J. NASON, a citizen of the United States,residing at South Berwick, in the county of York and State of Maine,have invented certain new and useful Improvements in Sash-Fasteners; andI do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to sash-fasteners.

My object is to provide a sash-fastener of extremely simple and cheapconstruction whereby the sash can be quickly and easily locked at anydesired height; and having this object in View the invention consists ofa sash lock or fastener of improved construction, as will appear morefully hereinafter.

In the accompanying'drawings, Figure 1 is a view showing the device inuse; Fig. 2, a top section showing the parts in detail; Fig. 3, a detailperspective view'showing the device in use.

The numerals 1 and 2 designate the meeting-rails of the two sashes, and3 is the center rail of the upper sash.

The numeral 5 designates a rod, preferably cylindrical, which is securedto the top rail of the upper sash at 6. A plate 7 is connected to thelower end of this rod and fastened to the meeting-rail of the upper sashby screws 8, said plate being notched at 9 for the reception of theupright rail 3.

The numeral 10 designates another plate, which is connected to themeeting-rail of the lower sash by screws 11. There are twoclamping-levers 12 and 13, which are pivoted on separate pins 14 and 15,which connect to the plate. It will be observed that these levers havenotched ends 16 on one side of their Serial No. 628,098. (No model.)

pivotal point, which receive the rod and are adapted to bindthereagainst.

The numeral 17 designates a spreader having a broad portion adapted tobe grasped by the finger and provided with opposite camfaces 18 and 19,adapted to bear against the inner faces of the longer arms of thelevers, said spreader being located between the levers and pivoted tothe plate at 20.

Assuming that the upper sash is fixed in its frame so as to beimmovable, the operation is as follows: The lower sash can be raised toany desired'height, the ends of the levers sliding freely on the rod,and when the proper point is reached the spreader is twisted,whereuponthe cams on said spreader engage with the levers and force their longerarms apart, thereby causing their shorter arms to firmly grip the rodconnected to the upper sash, and hence the lower sash may be sustainedat any point. On the other hand, the lower sash may be secured and theupper sash can be operated.

Having thus described the invention, what is claimed as new, and desiredto be secured by Letters Patent, is

In a device of the class described, the combination with a rod securedto one sash, of pivoted levers carried by the other sash and providedwith portions adapted to grip the rod, and a pivoted spreader locatedbetween the free arms of the levers and adapted for turning to cause thesaid levers to grip the rod.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
